This adjustment allows for the edge or lavatory. polishing of the Corian® Quartz cutout. Overview 2. Smooth any rough edges around the cutout with a medium This Technical Bulletin describes recommended fabrication techniques sandpaper or 800+ grit diamond hand pad to remove any chipping that can be used to integrate an undermount Corian® Solid Surface sink from cutting. If making the sink or bowl cut using a CNC router, or lavatory with a Corian® Quartz countertop or vanity top using Corian® most CNC tooling will provide an adequate cut and touch up may Joint Adhesive.

Fabrication Recommendations Corian® Quartz polishing techniques. The polishing process may overlap onto the Corian® Solid Surface sink or bowl slightly. Care The best method for fabricating the sink or bowl opening in the Corian® should be taken to avoid damage to the Corian® Solid Surface sink Quartz top will be determined by the type of sink or bowl chosen and the or bowl with the more aggressive diamond pads. equipment and tooling available to perform this step. Two methods are discussed here. The sink or bowl must be fastened to the rough factory 8. Mask off the polished Corian® Quartz edge with masking tape. Sand backside surface. Do not polish the area where the sink or bowl will be the Corian® Solid Surface sink or bowl until it is flush with the Corian® attached.
